Train operation control method, vehicle on-board controller, and train

A vehicle on-board controller (VOBC), comprising a memory, a processor, and a computer program stored in the memory, wherein the processor is configured to execute the computer program to perform operations comprising:

• receiving an instruction indicating permission to enter a train autonomous circumambulation system (TACS) control level of a train;
• determining whether the train satisfies a condition for entering the TACS control level;
• in response to that the train satisfies the condition for entering the TACS control level, controlling the train to enter the TACS control level and transmitting a TACS control notification to a ground device in a route section in which the train is located, the ground device communicating with the train through the TACS control notification based on a TACS control level protocol;
• and
• operating the train based on the TACS control level, wherein
• when the train is under the TACS control level, a driving mode of the train comprises an automatic train protection mode (CM), an automatic train driving mode (AM), and an autonomous train operation mode (SAM);
• when the train is under a communication based train control (CBTC) control level, the driving mode comprises the CM and the AM;
• when the train is under a point control level, the driving mode comprises the CM and the AM;
• and
• when the train is under an interlock control level, the driving mode comprises an emergency unrestricted train operating mode (EUM) and a restricted manual mode (RM).
